This document discusses a document store oriented database written in Clojure. It handles Clojure structures and uses Extensible Data Notation. The database is fast, with read speeds of 8K and write speeds of 4K using a proper thread pool. It has concurrency support and an architecture overview. Examples are provided of inserting, selecting, and querying data. Limitations include a 1MB document size limit and 2GB collection size limit.

12.  Replication, distribuited servers?
 Simple to use, install and develop
 Limitations
 1MB document size
 2 gb collection size
 240 Char to index path
